Medical Manipulator

摘要

A medical manipulator wherein a first section provided with a driven coupling is detachably attached to a second section provided with a driving coupling that includes a drive source and is driven by the drive source. The driving coupling and the driven coupling are fitted to each other to transmit the drive force from the drive source to a tip-end operation part. In at least one coupling among the driving coupling and the driven coupling, tooth ends on the side where the fitting of the driving coupling and the driven coupling begins when the first section and the second section are connected become thinner towards the axial-direction end surface.

1. A medical manipulator comprising:
a handle; a shaft that is extended from the handle; a distal end working unit capable of operating with respect to the shaft; and a drive source for operating the distal end working unit; wherein: a first portion, which includes the distal end working unit and the shaft and on which a driven coupling is disposed, and a second portion, which includes the drive source and on which a drive coupling that is driven by the drive source is disposed, are capable of being attached and detached; in a state in which the first portion and the second portion are connected, the drive coupling and the driven coupling are fitted together, and a driving force of the drive source is transmitted to the distal end working unit; and on at least one of the drive coupling and the driven coupling, a tooth-end portion, on a side that initiates fitting between the drive coupling and the driven coupling when the first portion and the second portion are connected, becomes narrower toward an end surface thereof in an axial direction.
